Abstract

This invention describes a flexible programmable build board with the associated hardware suitable for automated harness cable assembly. An automated cable assembly system essentially consists of a robot and a "universal", programmable build board 1. Wire path information in an automated system resides in the robot controller or the cable manufacturing cell processor. The robot is used to set up the cable path wire guide for a specific cable (Fig. 1). In addition, the build board must accommodate all fixtures and hardware required to build a harness cable. The build board 1 consists of several elements: a planar board with a grid of holes, wire guides, wire holders, and fixtures for connectors. A typical build board may be 1500 x 3500 mm, providing a multiplicity of holes in a fixed pattern.

Build Board System for Automated Harness Cable Assembly

This invention describes a flexible programmable build board with the associated hardware suitable for automated harness cable assembly. An automated cable assembly system essentially consists of a robot and a "universal", programmable build board 1. Wire path information in an automated system resides in the robot controller or the cable manufacturing cell processor. The robot is used to set up the cable path wire guide for a specific cable (Fig. 1). In addition, the build board must accommodate all fixtures and hardware required to build a harness cable. The build board 1 consists of several elements: a planar board with a grid of holes, wire guides, wire holders, and fixtures for connectors. A typical build board may be 1500 x 3500 mm, providing a multiplicity of holes in a fixed pattern. A preferred hole pattern follows an orthogonal coordinate system. A typical hole spacing is 25.0 mm. A critical element in automated harness cable assembly is the wire guides or pegs. Their function is to provide temporary retention of the wire bundle until the bundle is tied and formed into a permanent assembly. The peg described meets all the above-listed requirements. Two adjacent pegs 2, shown in Fig. 1, provide the cable build-up cavity 3. Three components make up a peg: the peg body 4, the cap 5, and a helical spring 6. The cap 5 is movably attached to the peg body by means of the helical spring 6. The articulating...
